如何使用VB.NET通过本地IIS服务器发送邮件 [英] How do I send mail through my local IIS server using VB.NET
问题描述
当我使用visual studio 2013发送电子邮件时它可以工作，但相同的代码在visual studio 2015中不起作用。
请帮助！
我也尝试更改端口号但不起作用。
任何将被赞赏，在此先感谢
我尝试过：
Dim s As String
s = vbNewLine
Dim targetURL作为字符串
targetURL =http：//xyz.aspx
Dim client As New SmtpClient（）
client.Host =abc .mail.com
Dim sendTo As New MailAddress（wer.mail.com）
Dim from As MailAddress = New MailAddress（qwe.mail.com ）
Dim message As New MailMessage（from，sendTo）
message.IsBodyHtml = True
message.Subject =Rejoining Approval
'message.SubjectEncoding
昏暗的身体作为字符串
body =尊敬的爵士& vbCrLf&
我想通知你&空间（2）& & cmbdropdownlist.Text& &空间（2）& 已被辞退&空间（2）& & cmbUnit.Text& & vbCrLf&
并希望重新加入& vbCrLf&
所以，请通过以下链接对其采取适当的行动。 &安培; vbCrLf&
& targetURL& & vbCrLf&
谢谢与问候& vbCrLf&

client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network
Dim basicAuthenticationInfo As New System.Net.NetworkCredential（qwe.mail.com，erty）
client.UseDefaultCredentials = False
client.Credentials = basicAuthenticationInfo
client.Port = 25
client.EnableSsl = True
'尝试
client.Send（消息）
MsgBox（ 重新加入信息已成功发送给高级，MsgBoxStyle.Information）

推荐答案
这些是SMTP编程中的一般性问题，不仅仅是在.NET框架中，而是几乎在每个平台上，因为服务器需要我们的东西，我们不提供这些内容苦恼的。需要考虑的一些事项是确保将SMTP服务器配置为接受从控制面板发送电子邮件的请求。您应该使用任何提供程序（例如Gmail或Outlook）尝试以下代码，并查看它们是否正常工作。
These are a bit general problems in SMTP programming, not just in .NET framework but almost in every platform because the server requires something out of us, and we are not providing those content details. A few things to consider are to make sure that your SMTP server is configured to accept the requests to send email from control panel. You should try the following code with any of the provider, such as Gmail or Outlook and see if they work correctly.
' You should use a using statement
Using client As New SmtpClient("<smtp-server-address>", 25)
' Configure the client
client.EnableSsl = True
client.Credentials = New NetworkCredential("<username>", "<password>")
' client.UseDefaultCredentials = true;
' A client has been created, now you need to create a MailMessage object
' From field
' Recipient field
' Subject of the email message
' Email message body
Dim message As New MailMessage("from@example.com", "to@example.com", "Hello", "World!")
' Send the message
client.Send(message)
'
' * Since I was using Console app, that is why I am able to use the Console
' * object, your framework would have different ones.
' * There is actually no need for these following lines, you can ignore them
' * if you want to. SMTP protocol would still send the email of yours.
' Print a notification message
Console.WriteLine("Email has been sent.")
' Just for the sake of pausing the application
Console.Read()
End Using

代码被捕获并从我的文章转换而来，通过.NET框架发送电子邮件，以及一般问题 - 使用C＃代码 [ ^ ]在文章的最后我讨论了一些问题，发送邮件失败就是其中之一。在您的代码中，我看到没有问题：1）主机名中没有http。 2）使用25端口。 3）用户名/密码设置。
问题应该在服务器上，检查是否允许您发送电子邮件;它将在SMTP服务器的控制面板下。否则，为任何其他提供程序尝试相同的VB.NET代码; Gmail，Outlook并查看结果。
The code was captured and converted from my article, Sending emails over .NET framework, and general problems – using C# code[^] and at the end of that article I talk about a few problems and "Failure sending mail" is one of them. In your code, I see no problem: 1) No http in hostname. 2) 25 port used. 3) username/password set.
The problem should be on the server, check that you are allowed to send the emails; it would be under the SMTP server's control panel. Otherwise, try the same VB.NET code for any other provider; Gmail, Outlook and see the results.
